Can solid be formed if surfaces overlap Solidworks
If surfaces overlap one another can a solid be formed if the surfaces enclose a solid
Unfortunately you'll need to trim the excess surfacing off using the trim tool, then use the "Knit Surface" command.
When using the "Knit Surface", you'll have an option to create a solid body if your surfaces are "Water-tight"; seamed properly.
If the option is not available, there is something wrong with your geometry.
"Pierce Point" relations are your best friend making solids from surfaces.
Hope this helps :)
